jobserver increase memory

hi,
i want to allocate more memory for one job, which is run on TAC, so i tried to add JVM parameter,
but it didn't work, i can't allocate more than 1024M...
i changed the tomcat configuration (JAVA_OPTS="-Xms256M-Xmx20480M"), it works, i can see in tomcat server status that the max memory is now 18205.50 MB.
But i think that i have to change some parameter on jobserver configuration, how
can i do this ?

regards,
John

Re: jobserver increase memory

Hi John
Welcome to Talend Community!
What'is the volume of your machine's memory?
The value of xmx cannot exceed the RAM.

Re: jobserver increase memory

Hi John
If you want to allocate more memory for one job, you can modify it in TAC->Job Conductor->JVM parameters as the following image.
There is no need to change configuration of Job Server.

Re: jobserver increase memory

Hi
I use the tool jvisualvm to monitor the JVM parameters for one Talend job.
In my local machine, I can increase the value of XMX larger that 1024M.

Re: jobserver increase memory

This is a really useful component.  Excuse my ignorance but what is the output telling me?
tMemoryMonitor_1: using 2347MB/3217MB (max=3641MB/64%) (processors=2)
<Name of the component>: <current memory use>/<?> (<max memory use allowed>) (<number of processors>)
The value after the "/" what is that?
